• Assess BP, HR, and respiratory rate before and periodically during administration. If respiratory rate <10/min, assess level of sedation. Dose may need to be ↓ by 25–50%. Respiratory depression does not ↑ in severity, only in duration, with ↑ dose. Monitor for respiratory depression, especially during initiation or following dose ↑; serious, life-threatening, or fatal respiratory depression may occur. May cause sleep-related breathing disorders (central sleep apnea, sleep-related hypoxemia).

• Pain: Assess type, location, and intensity of pain prior to and 1 hr (peak) following administration. When titrating opioid doses, ↑ of 25–50% should be administered until there is either a 50% ↓ in the patient’s pain rating on a numerical or visual analogue scale or the patient reports satisfactory pain relief. A repeat dose can be safely administered at the time of the peak if previous dose is ineffective and side effects are minimal.
  • Patients taking extended-release hydrocodone may require additional short-acting or rapid-onset opioid doses for breakthrough pain. Doses of short-acting opioids should be equivalent to 10–20% of 24 hr total and given every 2 hr as needed.
  • Assess for opioid-induced hyperalgesia, which can appear as ↑ levels of pain upon increasing the dose of the opioid, ↓ levels of pain upon decreasing the dose of the opioid, or pain from ordinarily nonpainful stimuli (allodynia). This condition is different from tolerance. If a patient is suspected to be experiencing opioid-induced hyperalgesia, consider ↓ the dose of the current opioid or switching to a different opioid analgesic.
  • An equianalgesic chart (see Equianalgesic Dosing Guidelines) should be used when changing routes or when changing from one opioid to another.

  • Prolonged use may lead to physical and psychological dependence and tolerance. This should not prevent patient from receiving adequate analgesia. Patients who receive opioids for pain rarely develop psychological dependence. If progressively higher doses are required, consider conversion to a stronger opioid. Prolonged use of opioids should be reserved for patients whose pain remains severe enough to require them and alternative treatment options continue to be inadequate. Many acute pain conditions treated in the outpatient setting require no more than a few days of an opioid pain medicine.

  • Assess risk for opioid addiction, abuse, or misuse prior to administration. Abuse or misuse of extended-release preparations by crushing, chewing, snorting, or injecting dissolved product will result in uncontrolled delivery of hydrocodone and can result in overdose and death. Hysingla ER is an abuse deterrent formulation that is difficult to crush and, if crushed, results in a gel.

• Cough: Assess cough and lung sounds during antitussive use.

Lab Test Considerations:

• May cause ↑ plasma amylase and lipase concentrations.

Toxicity and Overdose:

• If an opioid antagonist is required to reverse respiratory depression or coma, naloxone is the antidote. Dilute the 0.4-mg ampule of naloxone in 10 mL of 0.9% NaCl and administer 0.5 mL (0.02 mg) by IV push every 2 min. For children and patients weighing <40 kg, dilute 0.1 mg of naloxone in 10 mL of 0.9% NaCl for a concentration of 10 mcg/mL and administer 0.5 mcg/kg every 2 min. Titrate dose to avoid withdrawal, seizures, and severe pain.
